The Random Color Texture generates a random float value based which can be used to create color variations on instances of geometry. It's a simpler version of Instance Color texture. The Random Color Texture has a single parameter which is the Random seed value. Changing this value shifts the random output of the texture.
how to use
MAKE COLORFUL Cubes USING OCTANE SCATTER OBJECT
Open the Node editor and prepare the setup as you see in the picture below. In this setup, Random Color and Gradient nodes are connected to the Diffuse channel of the material. Gradient node is used because "Random Color" node has no color definition by default. It has a simple float function. There are number of cubes using Octane Scatter Object and Random Effector in the scene.
MAKE random greyscale Cubes usIng cloner
In the picture below, Random Color Texture is applied to Cloner cubes without Gradient Node. The difference is that the "render instance" option of the cloner objects is turned on. Since each cloner instance is a random float, it becomes applicable. If Cloner's "render instance" option is turned off for this use, Random Texture will not function.
MAKE random greyscale Colors usIng obejct'S Instance
In the picture below, 7 different instances of Cube object were created using Cinema 4D's Instance option and all were grouped by ALT + G shortcut. Then, a random color setup material was assigned to the main group. You can also add random colors to these cubes by adding a gradient node to the node setup again.
